10 Best Backpack Coolers 2026 in the United States

The YETI Hopper M12 Backpack Soft Cooler is a solid choice for campers and hikers needing a reliable way to keep drinks and small food items cold on the go. It can hold up to 240 fluid ounces, roughly the size needed for about 20 cans, which is handy for day trips or small gatherings. Its ColdCell insulation uses closed-cell foam that does a great job maintaining chill for hours, so your beverages stay refreshingly cold. The DryHide shell is made from tough, puncture-resistant vinyl that also protects against sun damage, making it durable enough for outdoor adventures.

One standout feature is the MagShield Access - strong magnets form a leak-resistant seal while allowing easy access to your items, which helps prevent spills but keeps the cooler securely closed when needed. The backpack design includes comfortable multiple carry handles and a practical kangaroo pocket outside for small essentials like keys or a phone. However, at around 3 kilograms (6.7 pounds), it might feel a bit heavy when fully packed, especially if you’re hiking long distances. Also, while it is leakproof, users should still handle it carefully to avoid messes.

Its size is perfect for personal use or small groups but might be limiting if you want to carry larger quantities or bigger items. The YETI Hopper M12 Backpack offers excellent insulation, durability, and smart features that suit outdoor enthusiasts looking for a dependable cooler backpack that balances comfort with tough materials.

The Hydro Flask Cooler Backpack offers a solid 20-liter capacity, enough to hold about 38 cans, making it a great choice for beach trips, travel, or outdoor activities like camping and hiking. Its insulation keeps contents cold for up to 24 hours when combined with ice packs, which is impressive for a soft cooler in this size range. Weighing just 2.49 pounds, it’s relatively lightweight, and while it includes a removable cross-body strap for carrying, it does not have padded shoulder straps like a traditional backpack, which could influence comfort on longer walks.

Made from 100% recycled polyester with a water-resistant coating, the cooler provides good durability and protection from light moisture. The compression-molded lid and base help maintain its shape. Its large, zippered top allows easy access and cleaning, and the leakproof lining prevents spills from soaking through. This cooler backpack is ideal for those seeking reliable insulation and durability in a simple, easy-to-carry design, though it may not be the best choice for those needing multiple compartments or maximum carrying comfort for extended hikes.

The Maelstrom 35 Can Backpack Cooler is a versatile and practical option for outdoor enthusiasts. It offers a significant capacity, capable of holding up to 35 cans, making it suitable for activities such as camping, fishing, hiking, and picnics. The high-density insulation and leak-proof liner ensure that your food and drinks remain hot or cold for up to 16 hours, which is a strong point for preserving freshness during long outings. The interior is also easy to clean, adding to its convenience.

Weighing only 15.2 ounces, it is lightweight and easy to carry. The backpack features multiple compartments and pockets, including a main zipper compartment, front pockets, mesh side pockets, and a hidden back zipper pocket, providing ample storage and organization options. Comfort is prioritized with thicker, padded back support and adjustable, breathable shoulder straps that distribute weight evenly and reduce fatigue.

Additional features such as a stainless steel bottle opener, condiment bottle storage, and various hanging points for tools and accessories enhance its functionality. However, the polyester material, although durable, may not be as robust as other heavy-duty fabrics and the adjustable buckle for wine bottles might not be suitable for all bottle sizes. Some users may find the size a bit bulky for shorter trips or daily use. In summary, this backpack cooler excels in capacity, insulation, and comfort, making it a great choice for extended outdoor activities, although its durability and versatility in carrying different items could be slightly improved.
